TELEGRAPH OR ELECTRIC WIRE POLIE.V

Specification of Letters Patent.

Patented July 16, 1907.

Application sied November 2s, i906. serial No. 344,706.

.To all whom it may concrn:

distance transmission-lines.

The object of the invention is to produce a pole which shall be durable, though simple in construction, and which is provided with improved means for attaching the arms or cross trees to the body of the pole.

The invention consists in the construction and combination of parts to be described more fully hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forining' a part of this specification, in which similar characters of reference indicate corresponding parts in all the gures. f

Figure l is substantially a side elevation of a pole constructed according to my invention, showing the foundation of the pole in cross section; a portion of one ofthe arms is represented as broken away, and so is a portion of the body of thepole; Fig. 2 is a cross section on the line 2 2 of Fig. l and illustrating the manner of attaching the arms to the pole; Fig. 3 is a cross section on the line 3-'3 of Fig.. l and illustrating especially` the construction of the arm; Fig. 4 is a cross sectonon the line 4-4 of Fig. l and further illustrating the manner of attaching the arm to the pole; Fig; 5 is a side elevation ofthe upper portion of the pole and illustrating a form of mounting for an insulator where the ypole is not provided with an arm and is intended to carry a single conductor or line', and Fig. G is an edge or endelevation of the mounting shown in Fig. 5.

Referring more particularly to the parts, 'l represents the body of the pole, which is preferably formed of channel iron, presenting substantially the cross section of a capital H, as shown in Fig. 4. This pole body may be formed of asingle structural shape such as an Ibeam of commerce having special or extended flanges -2. In practice, however, the pole body may be formed by attaching, back to back, a pair of channels, the flanges of which project in opposite directions. At its upper portion, the inges 2 of this pole are provided with notches 3 disposed in pairs and opposite to each other ,as indicated. These notches are for the purpose of facilitating the attachment of a cross tree or arm 4, the construction of which is very clearly shown in Figs. 2 and 3. This arm is formed of two oppositely disposed parallel Z-beams 5, the lower lin any pair of the alining notches 3.

flanges G whereof project inwardly and areI received The pairs of notches are disposed vertically at a suitable distance apart to insure the proper insulation between the conductors carried by the different arms when more than one arm is attached to the pole. The lower flanges 6 which engage the notches 3 are provided, themselves,

with notches or recesses 7, indicated in Fig. 4, which register'with the notches 3 as shown. The Z-bars or beams 5 are connected together by through bolts 8 by means of which the bars may be clamped firmly against the edges of the flanges 2 of the pole body. These bolts 8 are preferably disposed quite close to the pole body, as indicated in Fig. l.

Near the outer ends of the arm 4, blocks 9 are provided, which are preferably formed of Wood or similar material and these blocks are heldin position between i the bars 5 by means of through bolts l0 which pass through them as shown. The upper faces of the blocks 9 are flush with the upper faces of the upper flanges llf of the Z-bars, but the block does not exten'd down to the flanges 6, from which arrangement a space is proas to enable them to attach insulators in any suitabley manner.

The arm 4 is braced near its extremities by inclined diagonals or braces 14, which are preferably of the form of tee-irons, the webs l5 of which are cut away at the ends of the braces so as to Afacilitate their attachment to the arm and the body of the pole, asindicated.

In addition to the bolts 8 at the point of attachment of the arm to the pole, I provide similar bolts,8n which pass through the web 1G of the pole body, and through the Z-bars also, as shown very clearly in Fig. 4. With the arrangement described, evidently the pole body may b e provided with a plurality of notches, any pair of which 'may be selected as a seat for the arm, and' where a number of arms are to be attached to the same pole, these notches will be located at a suitable distance apart facilitating the quick attachment of the arms.

The lower extremity of the pole l is stepped in a foundation or base 17 of concrete or cement, so that the pole is held very rigidly in an upright position. Sometimes it is not intended that the pole should carry more than one line wire, and under these circumstances'I lower portion of which is formed of two oppositely disposed channels 2l, the lower flanges 22 whereof project toward each other, and are provided with notches similar to the notches 7 which engage the notches 19; the arrangement being such that the inn er faces of the channels` will seat against the edge of the flanges of the pole. These channels 2l are rigidly held in position by through bolts 23 which pass across near the sides of the pole. Upon kthe upper anges 24 I attach the lower flanges ot' Z-bars 25, and the flanges 26 at the upper portions of these Z-bars project outwardly, as shown. In addition to the rivets or bolts 27 which attach the Z- bars to the flanges 24, I provide butt-plates 28 which lap over the joint and which are riveted or bolted to the ,webs of the Z-bars and the channels so as to form a very rigid structure. Between the Z-bars there is mounted a block 29 which constitutes a seat for the insulator, the upper lace of the block being flush with the upper faces of the flanges 26 as indicated. Beneath the block 29, a removable slide 30 is provided, similar to the slides 12 described above. The manner o mounting the holding bolt for the insulator in this forni of the invention is the same as that described above and shown in Fig. l.

The notches 3 effectually prevent any tendency oi the arm or the mounting from sagging down on the pole body. At the saine time, the notches which are provided in the channels or Z-bars prevent any tendency Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A pole having a body presenting outwardly projecting flanges with notches therein, bars having ilang'es prescntingr notches engaging said Iirst notches, means for clamping said bars against the side oi' said pole, and means whereby said bars may form va scat for au insulator.

2. A pole having a body with bars rigidly attached thereto, a block attached between said bars and constituting a seat for an insulator, fastening devices passing upwardly through said block, and a slide disposed under said fastening devices and removably held between said bars.

3. A pole having a body, bars rigidly attached thereto and presenting inwardly projecting ilanges, a block mounted between said bars, fastening devices mounted in said block for attachingr an insulator thereupon, -and a slide adapted to be slid into position under said block and resting on said ilanges.

4. A pole presenting outwardly projecting ilanges having notches therein, an arm formed of oppositely disposed Z-bars having inwardly projecting flanges at the lower edges thereof, said flanges presenting notches engaging said first notches. means for clamping said Z-bars to said body, blocks mounted between said Z-bars and constituting seats for insulators, bolts passingupwardly through said blocks to attach the insulators, and slides disposed beneath said blocks and resting on said flanges.

In testimony whereof I have signed my name to this speciiication in the presence of two subscribing witnesses.
